Embodiment Construction
[0028]In FIG. 1, reference numeral 500 represents 400° F. air; 501 represents 50-200 mph. Referring now to FIG. 2, the new stand-alone ground based hybrid deicing system 10 of the present invention, (shown in detail in FIG. 7), utilizes a specially constructed coaxial nozzle assembly 20 that simultaneously delivers two independent, high velocity deicing streams. Preferably, a deicing fluid stream is encased within a high velocity airstream. The nozzle preferably has a special 0.060 inch diameter jetting orifice that produces a conical shaped jet. (in FIG. 2, reference numeral 400 represents heated deicing fluid from the triplex pump; 401 represents pressurized air from the centrifugal compressor (100 Lb per min); 402 represents 800 mph airstream; 403 represents 800 mph deicing fluid stream (high pressure / low flow mode); and 31 represents ASME “long radius” nozzle.)
[0029]The coaxial nozzle assembly 20 is specially designed to meld two fluid flow technologies, conversion of subsonic a...
